The Polaris A3 Missile awaits its first flight test from the Cape. A few days later, U.S. President John F. Kennedy would sign the DoD Fiscal Year 63 Appropriations Act authorizing constructions of five additional fleet ballistic submarines to be fit for the Polaris A3 ballistic missile body. Today, the Sea-Based Strategic Deterrence mission continues. The current generation of submarine launched ballistic missile—the Trident II D5/D5LE—along with the Intercontinental ballistic missile and nuclear capable bombers create the nation’s strategic nuclear deterrence capability. The triad of capabilities – SLBMs, ICBMs and nuclear capable bombers – are each undergoing modernization to ensure our nation’s ability to serve as the backbone of our nation’s security. The U.S. Navy Strategic Systems Programs (SSP) mission remains ever vital for the safety and security of the U.S. and her citizens at home and abroad. (U.S. Navy Photo/Released)
